Investigation of resonant Raman scattering in type II GaAs/AlAs superlattices by H Choi( )

1 edition published in 2001 in English and held by 0 WorldCat member libraries worldwide

GAMMA-related Type I outgoing RR spectra within several theoretical models. Thereby, the mechanisms of the Type II RR scattering, the origins of the RR lineshape and the polarisation dependence, are fully explained, clarifying the spectral features observed in the GaAs zone-centre optic phonon region. The Type II resonance also allows the observation of zone boundary (X-point) phonons from intervalley (IV) scattering. A model of the IV electron-phonon interaction involving X conduction band electrons and zone boundary phonons in Type II SLs is presented. With the predicted SL selection rules for IV scattering, the simultaneous observation of both the zone-boundary longitudinal acoustic and optic phonons can be understood and the spectral features quantitatively explained. As a consequence of the band alignment in GaAs/AIAs superlattices (SLs) and the indirect nature of bulk AIAs, quantum confinement can be used to engineer a Type II system. This produces an electron population in the AIAs longitudinal (X sub z) or transverse (X sub x sub y) zone-edge states, which is separated in both direct and reciprocal space from the hole population in the GaAs zone-centre (GAMMA) states. This thesis is an investigation of the electronic and vibrational structure of Type II GaAs/AIAs SLs using theoretical models and spectroscopic techniques, with special emphasis on Type II resonant Raman (RR) scattering. The majority of this thesis concerns short-period GaAs/AIAs SLs with X sub z as the lowest conduction band state. A model of the SL electronic band structure is presented, including the effects of interband GAMMA-X sub z mixing and the X-point camel's back structure. Interband mixing makes GAMMA-X sub z radiative transitions observable in photoluminescence (PL) and RR experiments. Phonon-assisted transitions from the X sub z state are also observed in PL experiments. Several of the participating phonon modes are unambiguously identified, in good agreement with recent reports.
